Allow trackpad swipe to scroll in Catalyst apps

[tschmitz]

Goals :soccer:

In Mac Catalyst, most scroll views can be scrolled with a swipe gesture on the trackpad or mouse. (For instance, table views can be scrolled with a two-finger swipe.) Charts should be scrollable in the same way.

Implementation Details :construction:

Set the allowed scroll types and eliminated the number of touches requirement to allow scrolling via trackpad in Mac Catalyst.
